 **IMPORTANT:**
 
-This Github page **ONLY** includes the Matlab code for Fmask 4.4. **The Matlab package with GLOBAL AUXILIARY DATA (~1G)** is available at this [Google Drive](https://drive.google.com/file/d/1LzfZSW3Ku4nfr6aSfu-nR_zgygAiBXUD/view?usp=sharingg), where **autoFmask** is the main function for processing an image. **autoFmaskBacth** can process all Landsats 4-8 and Sentinel-2 images into a folder. Note that Mapping Toolbox in Matlab is required for using the source code.

(The directory of the auxiliary data \<AuxiData> usually is at the same location as the installed application, or copy the dataset from the MATLAB code package)**
 
 This 4.4 version has substantial better cloud, cloud shadow, and snow detection results for Sentinel 2 and better results (compared to the 3.3 version that is currently being used by USGS as the Collection 1 QA Band) for Landsats 4-8 . This version can be used for **Landsats 4-8 Collection 1/2 Level 1 product (Digital Numbers)** and **Sentinel 2 Level-1C product (Top Of Atmosphere reflectance)** at the same time.
